GAN OPENER.

Application mea November 17, 1927. serm No 233,780.

My invention. relates to can openers of the rotary impelled type.

One essential object of my invention is to enable the removal of the can top without incision of the blade into the side wall of the can or other mutilation of said wall.

Another object is to insure continuous and close engagement of the device with the can throughout the cutting operation.

Further objects are compactness, strength, and a minimum of constituent parts, inexpensively cut, bent from flat metalblanks, and easily assembled.

Invention resides in the means and mechanism for attaining the above ends falling within the scope of the appended claims.

In the accompanying drawings, illustrating-the principleof'my invention, and the best mode now known to me for applying that principle,

Figure 1 is a plan view of my opener applied to a can, the latter being shown fragmentarily, v. Figure 2, a front ,elevationl of the same,

Figure 3,a vertical section taken on line 3-3 of Figure 2,

Figure 4, a rear view of my device, showing in broken lines a fragment of the can to which it is applied, and in broken lines a second position of the operating parts,

Figure 5, a detail perspective of the swinging arm and the rotary parts mounted thereon, and

Figure 6, a front view of the carrier plate and pinion. y

Similar characters of reference indicate similar parts throughout the views.

In` detail my device comprises a. body or carrier plate 8 of substantially triangular outline with its greatest width at its top, and provided along the major extent of itstop with a rectangular rearwardly directed bearing lip 9. Adjacent the lip, and integral with the upper portion' of theplate at the forward extremity of the latter is a rearwardly and downwardly directed arched or hook-sha ed blade 11 whose vertical or depending extremity a transversely inclined beveled edge 15 terminating in a point 16 adjacent the lip 9.

The plate 8 is providediwith a vertically inclined arcute or quadrant shaped slot 20 having preferably curved ends, and whose uppermost forward end terminates adjacent the cutting edge 15 of the blade 11. Along ak portion 14 has upon its freethe upper edge of the slot are a. series of segmentally disposed teeth 22 terminating at a point short of the forward end of the latter.

. A flat arm 24 is pivoted at its lower end by a stud or pivot pin 26 to the lower end of the l provided with peripheral teeth 34 whichV are preferably diagonally arranged. Fast upon an intermediate portion of the shaft 3l is a pinion 3 6 whose teeth 37 are engagable with the teeth 22. Fast to the forward end of the shaft 31, which is preferably squared, is a disk or plate 39, with diametrically 'opposite ly disposed thumb portions or wings 40 integral therewith and disposed in a plane at right angles thereto, the whole constituting an, operating member indicated in a general way by 41.

In describing the operation of my device reference is made to the fragmentary showing of a cylindrical can wherein 43 and 44 are the side `and top respectively, and 45 the usual peripheral bead. To apply my device the point 16 of the blade 11 is placed upon the can top 44 and is forced downwardly therethrough by the following movement. The

arm 24 is initially in the rearwardly inclined position shown in broken lines in Figure 4.

The actuating member 41 is next rotated and as the pinion 36 travels along the rack the arm is thereby brought to an upright position, as indicated in full lines in Figure 4,

which movement brings the disk 33, which abuts against the side of the can, u? against the under side of the bead 45 and orces the blade point 16 through the can -top ready for 6. When, however, the cutting operation,is\

completed and it is desired to ldisengage the device from the can, it is necessary only to reverse the 'direction of rotation of the member 41, and the pinion teeth will reengage the rack teeth and while moving along the slot will elevate the plate 8 and blade 11.

I claim i 1. A can opener comprising a carrier plate provided with an opening, teeth on the plate extending into the opening, a blade upon the plate adjacent the opening, an arm pivotally mounted on the plate, a shaft on' the arm, a pinion on the 'shaft meshing with the teeth, an advancing disk upon the shaft adjacent the blade, and means for rotating the shaft.

2. A can opener comprising a carrier plate provided with an opening, a series of teeth upon the plate extending into the opening, avbearing lip upon the plate, a vertically disposed blade upon the plate adjacent the lip, an arm pivotally mounted upon the plate, a, shaft journaled in the arm, a pinion on the shaft engaging the teeth, an advancing disk fast to the shaft cooperating with the blade, and means for rotating the shaft.

3. A can opener comprising a carrier plate provided with an arcute opening, a series of teeth upon the plate projecting into the opening and extending nearly to the end of the opening, a bearing lip upon the plate, a blade' upon the plate adjacent the opening, an arm pivotally mounted on the plate, a shaft rotatably mounted in the arm extending through the opening, a pinion fixed to the shaft extending through the opening, a pinion fast to the shaft within the opening and enageable with the teeth, an advancing disk ast to the shaft adjacent the blade and cowith the plate adjacent the lip including a depending beak portion provided with a transversely inclined cutting edge upon rits lower extremity, an arm pivotally mounted upon the plate and movable over the slot, a shaft pivoted to the arm,a pinion on the shaft engageable with the teeth, an advancing disk upon the shaft parallel with the beak, and means for rotating the shaft. n l

5. A can opener comprising a earrieplate provided with an opening, a plurality of i teeth upon the body extending into the opening, a lateral bearing lip upon theplate above the opening, a blade upon the plate adjacent the lip and the opening, an arm pivotally mounted on the plate below the opening and movable over the Opening, ashaft rotatably mounted in the arm extending through the opening, a pinion fast to an intermediate portion of the shaft engageable with the teeth, an advancing disk fixed to one end of the shaft co-operating with the blade, a plate fast to the other end of the shaft, and wings upon the last mentioned plate.

In'testimony whereof I have aflixed my signature.
